Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT11032D is determined by strict equivalence across the following critical parameters:

• Logic function: Quad 2-input OR gate configuration
• Electrical specifications: Supply voltage range 4.5V ~ 5.5V, output drive capability 24mA, propagation delay 8.1ns @ 5V with 50pF load
• Input logic thresholds: Low 0.8V, High 2V
• Package format: 16-SOIC surface mount
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3, MSL Level 1

The 74ACT11032DR qualifies as a direct substitute based on identical electrical performance, logic configuration, and package specifications. The primary distinction is packaging format: the 74ACT11032D is supplied in Tube packaging, while the 74ACT11032DR is supplied in Tape & Reel (TR) format. Both maintain Active product status with full Texas Instruments support.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11032DR is the direct substitute for the 74ACT11032D. Both parts maintain identical electrical characteristics, logic functionality, and compliance certifications. The 74ACT11032DR carries Active product status from Texas Instruments, ensuring continued availability and support, whereas the 74ACT11032D is designated Last Time Buy with finite stock.

Selection between these parts is determined by packaging requirements and supply chain considerations. The 74ACT11032D in Tube packaging is suitable for lower-volume applications or manual assembly processes. The 74ACT11032DR in Tape & Reel format is optimized for automated pick-and-place assembly and high-volume production environments.

Both parts satisfy ROHS3 compliance and MSL Level 1 requirements, making them suitable for standard PCB assembly processes without moisture bake-out procedures.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11032DR directly replace the 74ACT11032D in existing designs?

A: Yes. The 74ACT11032DR is electrically and functionally identical to the 74ACT11032D. Both parts feature the same 16-SOIC package footprint, supply voltage range, logic thresholds, propagation delay, and output drive capability. No circuit modifications are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and lower-volume assembly. Tape & Reel packaging presents components on continuous carrier tape wound on reels, optimized for automated assembly equipment. Both formats contain identical die and electrical performance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 74ACT11032D and 74ACT11032DR maintain identical ROHS3 compliance status and MSL Level 1 rating. They are interchangeable from a regulatory and environmental standpoint.

Q: Why is the 74ACT11032D marked as Last Time Buy?

A: Last Time Buy designation indicates Texas Instruments has discontinued production of this part number. The 74ACT11032DR remains in Active production status, making it the recommended choice for new designs and ongoing supply requirements.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: logic function (quad 2-input OR gate), supply voltage (4.5V ~ 5.5V), output drive (24mA), propagation delay (8.1ns @ 5V, 50pF), input thresholds (0.8V low, 2V high), operating temperature (-40°C ~ 85°C), and 16-SOIC package format. All these parameters are identical between the main part and substitute.
